Why setResponseText in ResponseObject is depreciated?

I saw a depreciated flag in this methode. Does it mean it will be deleted on day ?

public class ResponseObject implements PerformanceResourceTiming, HttpMessage {
//[ ... ]
/**
     * Set the raw response text
     * 
     * @deprecated from 5.4
     * @param responseText the new raw response text
     */
    public void setResponseText(String responseText) {
        responseBodyContent = new HttpTextBodyContent(responseText);
        this.responseText = responseText;
    }
